SYMPTOM
mysql fails to start
IMPACT
no sql for you
DIAGNOSE:
service mysql start
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
- systemd has all sort of craziness going on so stop that
service mysql stop
- look at what apparmor is up to
tail -F /var/log/syslog | grep -i apparmor
- then start again
service mysql start
output is:
- mysql cannot read /etc/mysql

[Triage Notes]
This bug tracks reports of the following AppArmor denial:
Aug 7 18:22:17 c505 kernel: [ 1485.490459] audit: type=1400 audit(1470619337.926:98): apparmor="DENIED" operation="open" profile="/usr/sbin/mysqld" name="/etc/mysql/my.cnf.migrated" pid=11219 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=109 ouid=0
If you are seeing a denial of /etc/mysql/my.cnf.migrated in this manner, then the underlying issue may affect you too.
If you are seeing a denial of some other file, then you have some other AppArmor-related problem that is *not* the issue tracked in this bug. If you believe that your failure is a bug in Ubuntu, please look for other bugs and file a new bug if there isn't a matching one that tracks your different issue.
